Document Type and Number:
Japanese Patent JP2013220005
Kind Code:
A
Abstract:

To provide a motor and a concentrated power distribution member that reduce man-hours and parts count required for connecting bus rings and lead wires of coils of teeth.

A motor 1 includes: a stator 11 that has coils 111, 112, and 113 of multiple phases wound around a plurality of teeth 110; and first to third annular bus rings 21 to 23 that are arranged concentrically with the stator 11 and supply drive current to the coils 111, 112, and 113, respectively. The first to third bus rings 21 to 23 have respective lead wire insertion portions 21a, 22a, and 23a that allow first lead wires 111a, 112a, and 113a of the respective coils 111, 112, and 113 to be inserted therethrough and that are formed by bending respective metal conductors 211, 221, and 231. With the first lead wires 111a, 112a, and 113a inserted therethrough, the lead wire insertion portions 21a, 22a, and 23a are crimped so as to electrically connect the respective metal conductors 211, 221, and 231 to the first lead wires 111a, 112a, and 113a.
